jerzy Posted July 2 Share #21  Posted July 2 (edited) Advertisement (gone after registration) how would you then explain this image? It is a shape of perforation hole from a film layer laying above it - argument for light leak happening in film chamber. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Re ghost image along the whole lenght of the film - when you wind you hold usually camera differently than when shooting, orientation towards source of light is different . And Didier wrote as well that not all frame show this effect. Interesting would be to see that last stripe, this would possibly support or refute my diagnose. Edited July 2 by jerzy 2 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!

didier Posted July 2 Author Share #23  Posted July 2 Thank you all for your analysis and advice. Here is the beginning and the end of the roll (Kodak 400 Ultra) Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!   You see the pattern most starting picture 11 until 32. Not visible neither at the end of the film, nor at the beginning.   And now, a second Roll (Portra 160) I did a few weeks later. You will notice we almost don’t see the pattern… only on a few pics (the most visible is on pic 27A).  I wonder if is not also linked with the speed / EV : you see the thing most is strong light (blue sky, …).  Thanks again for sharing your analysis and knowledge  Didier 1 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!   You see the pattern most starting picture 11 until 32.

On cloudy day you might not see it at all. I would do the teast with strong torch/flashlight observing the film chamber Link to post Share on other sites More sharing options...

I am pretty upset at the job Leica Wetzlar did… Here are the full negs I got in the Mail today : the pattern is clearly visible. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!  For what it's worth, my IIIg was producing patterns on the film exactly like the repeating one at the bottom of the strips shown here, and covering the slow speed dial and about 1cm around it eliminated them. As did replacing the piece of felt on the inside of the shell near that area that a previous repairer allowed to fall out. Of course there may be other causes and other problems at the same time. 1 1 Link to post Share on other sites More sharing options...
jerzy Posted July 3 Share #26 Â Posted July 3 this is what I wrote in #7. Missing felt inside the shell is protecting against the light penetratring between the lens flange and vulcanite, Btw - space between lens flange and vulcanite shall be sealed as well with hard wax 1 Link to post Share on other sites More sharing options...

As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!  As you can see, it's a very distinctive pattern with a clear cause. This is from mine when it had the same problem- as Jerzy described, the missing felt inside the shell and poor coverage of vulcanite/black wax around the slow speed dial. It's an easy fix, though.  Edited July 5 by qqphot 2 Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!  As you can see, it's a very distinctive pattern with a clear cause.
